SENSOR SYSTEM, TRANSMISSION TERMINAL AND TRANSMISSION METHOD

Abstract

According to one embodiment, a sensor system, a transmission terminal, and a transmission method that can curb a decrease in time estimation accuracy are provided. The sensor system includes one more sensors, one or more transmission terminals, and a collection apparatus. The one or more transmission terminals include a first communicator and a second communicator. The first communicator transmits first transmission data including time information to be used for time estimation to the collection apparatus in a wireless manner. The second communicator transmits second transmission data including information acquired on the basis of the physical quantity sensed by the one or more sensors to the collection apparatus at a frequency different from a frequency used by the first communicator in a wireless manner. The collection apparatus includes a reception time determiner and a time information processor. The reception time determiner determines a plurality of reception times of a plurality of pieces of first transmission data transmitted from the first communicator. The time information processor performs the time estimation on the basis of the plurality of pieces of first transmission data and the plurality of reception times.
